Mercury's $200 million Series D closed in May 2026 at a $5.2 billion valuation, up 49% from the round it raised just 14 months earlier, led by TCV. The headline the company chose to lead with wasn't the valuation jump. It was four consecutive years of profitability on both a GAAP net income and EBITDA basis. That framing choice is the signal. Late-stage investors in 2026 are pricing profitability as the primary underwriting criterion again, and the companies raising know it.
The mega-rounds are masking a tighter market
The headline numbers look generous. PitchBook counts $274.2 billion in venture-growth capital deployed through May 2026, already more than double the full-year 2025 total. But 86.4% of that figure traces to just four rounds, all from three foundation-model companies: OpenAI, Anthropic (twice), and xAI. Strip those out and the growth-stage market for every other company looks a lot closer to the tight, selective environment behind the 2023 down-round peak than a broad reopening.
What's flowing to the non-frontier-lab majority is going to companies that can show the same thing Mercury did: durable, disclosed profitability, not a growth curve and a story about a path to one.
Profitability is necessary, and provably not sufficient
Databricks is reportedly in talks for a new private round at a $165 billion to $175 billion valuation, up from the $134 billion mark set in its own February 2026 round, according to Tech Insider's reporting on The Information. The pitch behind that markup is positive free cash flow over the trailing twelve months, layered on top of a $5.4 billion annualized revenue run-rate growing more than 65% year over year. Growth plus proof of cash generation, not growth alone, is what cleared a markup of that size.
Klarna is the harder lesson in the same data set. The company posted Q1 2026 revenue of $1.0 billion, up 44% year over year, and swung to $17 million in operating income from a $90 million loss in the same quarter a year earlier, with adjusted operating profit at $68 million against $3 million previously, according to its own investor release. By any of the metrics Mercury led with, Klarna qualifies as profitable. Its stock had still fallen more than 45% since the start of 2026 on investor concern over the tradeoff it made to get there. Hitting the profitability number does not automatically buy the market's trust in how you got there or whether you can keep growing at the same time.
Institutional capital is repositioning around the same bar
Benchmark, a firm that held a strict $425 million fund-size discipline for more than 20 years, closed $2 billion across two new funds in June 2026, including a $1.25 billion vehicle dedicated entirely to later-stage investments, its first growth fund ever, according to TechCrunch. A firm that built its identity on staying small and early is now building dedicated capacity to write checks into companies that look like Mercury and Databricks: proven, later-stage, cash-generating.
The rest of the market data backs a return to discipline rather than a return to 2021. Carta reports the down-round rate fell to 11.4% in Q1 2026, back in line with 2019 and 2020 levels and well off the 22% peak hit in 2023. At the same time, median late-stage post-money valuations hit a record $35.9 million at mid-2026, per PitchBook, as capital concentrates into fewer, more mature companies rather than spreading across a wider field of later-stage bets.
What to do with this before your next raise
The operating question changed. It is no longer just what your growth rate is. It's whether you can put a profitability disclosure on the same slide as that growth number and have both hold up under scrutiny.
Mercury proved that's possible. Klarna's numbers show it's harder than it looks, since profitability alone didn't stop a 45% stock decline. This week: pull your trailing twelve months of GAAP net income and EBITDA, not just ARR growth, and decide now which one you'd lead a term sheet conversation with. If the honest answer is neither, that gap is the thing to close before you're in the room, not during the raise.
